That is pretty cool. And what is it with these things, anyway, people suggest I sell mine almost every time I take it out, what's up with that? I haven't even finished it yet. That might be convenient, though, I already have ideas that would pretty much mean starting over, like a 4 stroke engine, for starters. I suppose I should be used to it, I'm constantly on the move from project to project, building really cool things that you just can't buy. Sometimes I part with them, I traded one for the bicycle I used for this project, it was my super stun gun, using 2 of the biggest transformers I could buy, then driven by a couple of lithium batteries. It was really scary, way more than a stun gun really needed, or that any I have ever seen had. I built a 6 watt 450nm (blue) laser using a model of a Star Trek phaser for a host, everybody wants one of those, too. It starts fires. You just have to love a "laser pointer" that leaves a smoking black burn line behind the dot. I used the most powerful visible spectrum laser diode made, the NUBM44, so I guess I'll build another one when they come out with something even more powerful.
